XF 2.1 A forum search box with auto-complete

[Orit]

Hello
Has anyone managed to create a forum search box with auto-complete
like the following (from XF1.0):

AutoComplete for Other Data?

I would like to create an autocomplete dropdown for things other than username (i.e. Forum Title). I noticed that the AutoComplete function only allows you to use username, since it is including the username and avatar URL. How would I go about doing this? Do I need to write my own AutoComplete...

Thanks!
